To find the missing tip amount, we need to first calculate the total sum of Yasmine's tip earnings over the 8 nights of work.
Total sum of tip earnings = $35.80 + $79.60 + $38.10 + $20.50 + $10.45 + $96.78 + $45.90 + x
Sum = $67.08 + x
We know that the mean earnings in tips over 8 nights is $46, so we can set up the following equation:
Mean earnings = Total sum of tip earnings / Number of nights
$46 = ($67.08 + x) / 8
Solving for x:
$46 * 8 = $67.08 + x
$368 = $67.08 + x
x = $368 - $67.08
x = $300.92
Therefore, the missing tip amount is $300.92.
